Over-medicated by thyroxine - felt so ill :-(

From: Lizzie1976 - 5 years 14 weeks ago

Hi everyone. I had been hypo for around 8 years (I'm 35) and have always been on 75 mcg thyroxine every day. This was until a month ago when my gp increased my meds to 100. A week into the increase I began to feel ill with nausea, diarrhoea, agitation, nervousness. At first I didn't realise it was my meds and thought I had some sort of virus. Then I began to get night sweats and felt over heated at times during the day. Then one night I vomited. After having various other blood tests done it dawned on me about my increase in meds I mentioned it to my gp and he said I had presented some symptoms of hyper, well I think I had most of them! It also caused my period to arrive 5 days early.

I am writing on here today because I would like to know if anyone else has been through similar? I have been practically housebound for a month because I have felt so poorly and anxious. I have slipped into a bout of depression and trying to stay calm and focus on getting better. Also does anybody know - I was on 100 mcg for a month and had the last one 3 days ago when is the thyroxine likely to have left my system?

I also feel so exhausted now is this all normal?

Many thanks for listening xx

Hi,

I was just started on a T3 thyroid drug - Don't know the name off the top of my head. I was low but not super low so she started me on 5 mcg and we are going to adjust as needed.

She warned me that once I start (just started today) if I feel extreme nervousness or anxiety, palpitations etc to stop it. She told me this meant my body didn't need it. ( we are still trying to see if my symptoms are thyroid related or a bit of this and that) my TSH and T4 were "in the normal range" but my T3 was low so we are trying this to see if it works.

I have though had a lot of anxiety and nervous energy in the past and I know how you feel, it's an absolutely awful feeling. I would get on the phone with your Dr and ask him/her if the dose is a bit too high... explain your symptoms, you should definitely not have to live like that.

Good luck and hang in there! : )

Hi, I have been prescribed 150 µg thyroxine for several months. Around a month ago I started feeling unwell which started as insomnia. I then started feeling paranoid, anxious and really tired. I couldn't concentrate at work and then I began having sweats and fainted at work. I put it down to a virus but then when I started having palpitations and shakiness of my hands I went to my GP to have my thryoid checked. The GP has dropped my dose to 125 µg but has told me this is a trial as it may need to go lower. I am starting to feel a bit better but like you am still anxious and tired. I can't believe how too much thyroxine affects your mind and your body.

I hope you are feeling better.
